* [PATCH net-next] bnx2x: Fix compilation when CONFIG_PCI_IOV is not defined
From: Ariel Elior @ 2013-01-02 13:36 UTC (permalink / raw)
To: David Miller; +Cc: netdev, eilong, Ariel Elior
This patch ifdefs out the use of PCI_IOV_RESOURCES which exists in the
kernel only when CONFIG_PCI_IOV is defined. There is no point in doing
the same for the invocation of SRIOV functionality in the driver as it
will be immediately failed by a kernel which was thus compiled.

I think the 88E1510 support was added by the Digilent guys (added to Cc) and
the 88E1116R support came from within Xilinx.
I agree that these are pretty straight forward changes and could go upstream in
their current form.

I took a look, and TBF does :
if (qdisc_pkt_len(skb) > q->max_size)
return qdisc_reshape_fail(skb, sch);
We have several choices :
1) Add a one time warning
2) cap dev->gso_max_size at Qdisc setup time
3) Re-segment the packet instead of dropping it (if GSO packet), and
call the expensive qdisc_tree_decrease_qlen() function.
4) remove max_size limitation

First, thanks for working on this issue.
It seems the real problem is the epi->event.events = event->events;
which is done without taking ep->lock
While a smp_mb() could reduce the race window, I believe there is still
a race, and the following patch would close it.
diff --git a/fs/eventpoll.c b/fs/eventpoll.c

Yes. I am hoping it is possible to do it without a lock there,
but your change is more obviously correct.

Please clarify that this (and other functions) only checks for an

It is no longer a semaphore, even if some kernel-doc in this file calls
it that. 'RTNL lock' would be better as it matches the function naming:
rtnl_lock() etc.

The '__' prefix normally implies doing less work than the un-prefixed
function but __netdev_has_upper_dev() checks all devices stacked above
dev whereas this only checks a single level. Therefore I think one or
both should be renamed.

There should be a blank line between the closing brace and the comment
for the next function.

It would be for example in ep_send_events_proc() doing :
if (epi->event.events & EPOLLONESHOT)
epi->event.events &= EP_PRIVATE_BITS;
And this could happen at the same time.

Hi, Michal,
We do have the Ethernet support for 88E1510 (used on ZedBoard) in our repository. The commit is
https://github.com/Digilent/linux-digilent/commit/ae635e5fff35e9fe5928b4aca7264a1e5313a6b8
Or, I can send the patch to you if you need.
Best Regards,

I think the 88E1510 support was added by the Digilent guys (added to Cc) and
the 88E1116R support came from within Xilinx.
I agree that these are pretty straight forward changes and could go upstream in
their current form.

That modification in ep_send_events_proc() is protected by ep->mtx
(as is ep_modify()), though. Maybe there are other places, but I
don't see it.

* [PATCH] bridge: Correctly unregister MDB rtnetlink handlers
From: Vlad Yasevich @ 2013-01-02 19:41 UTC (permalink / raw)
To: davem, shemminger; +Cc: netdev
Commit 63233159fd4e596568f5f168ecb0879b61631d47:
bridge: Do not unregister all PF_BRIDGE rtnl operations
introduced a bug where a removal of a single bridge from a
multi-bridge system would remove MDB netlink handlers.
The handlers should only be removed once all bridges are gone, but
since we don't keep track of the number of bridge interfaces, it's
simpler to do it when the bridge module is unloaded. To make it
consistent, move the registration code into module initialization
code path.

* [PATCH v2] p54pci: don't return zero on failure paths in p54p_probe()
From: Alexey Khoroshilov @ 2013-01-02 20:06 UTC (permalink / raw)
To: John W. Linville
Cc: Alexey Khoroshilov, Christian Lamparter, linux-wireless, netdev,
linux-kernel, ldv-project
If pci_set_dma_mask() or pci_set_consistent_dma_mask() fails in p54p_probe(),
it breaks off initialization, deallocates all resources, but returns zero.
Similar issue is if check for returned value of pci_resource_len() fails.
The patch implements proper error code propagation.
Found by Linux Driver Verification project (linuxtesting.org).

s/might be/is/
Strangely, I've bisected this seemingly networking-related issue down to
the following commit:
commit 1fb3f8ca0e9222535a39b884cb67a34628411b9f
Author: Mel Gorman <mgorman@suse.de>
Date: Mon Oct 8 16:29:12 2012 -0700
mm: compaction: capture a suitable high-order page immediately when it is made available
That commit doesn't revert cleanly on v3.7.1, and I don't feel
comfortable touching that code myself.
Instead, I disabled THP+compaction under v3.7.1 and I've been unable to
reproduce the issue without THP+compaction.
As I mention in http://mid.gmane.org/20121229113434.GA13336@dcvr.yhbt.net
I run my below test (`toosleepy') with heavy network and disk activity
for a long time before hitting this.
My disk activity involves copying large files around to different local
drives over loopback[1], so perhaps the duplicate pages get compacted
away? toosleepy also reuses the same 16K junk data all around.
[1] my full setup is very strange.
Other than the FUSE component I forgot to mention, little depends on
the kernel. With all this, the standalone toosleepy can get stuck.
I'll try to reproduce it with less...
(possibly relevant info, I don't expect you to duplicate my setup
as it requires many, many patched userspace components :x):
fusedav (with many bugfixes[2]) -> (FUSE device)
zbatery (Ruby 1.9.3-p362) -> omgdav (in zbatery process) -> (TCP)
MogileFS (patched[3]) -> (TCP)
cmogstored
The (zbatery -> omgdav -> MogileFS -> cmogstored) path is all userspace.
cmogstored uses sendfile and may talk to itself via MogileFS replication:
MogileFS(replicate) -> HTTP GET from cmogstored -> HTTP PUT to cmogstored
(MFS was designed for clusters, but I only have one machine right
now) MogileFS replicate does not use splice between sockets, just
read/write, cmogstored does not use splice (yet) either.
The stuck ppoll() I noticed is from Ruby (zbatery/omgdav) while the
send() was from fusedav (using neon).

I just confirmed my toosleepy processes will get stuck while just
doing "rsync -a" between local disks. So this does not depend on
sendfile or FUSE to reproduce.
